Abstract

This paper presents the evolution of Saharan dust advection when the PM10 (particles with an aerodynamic diameter below 10 μm) concentration exceeds standard limits in different Tunisian sites. Meteorological and concentration data (from 2004 to 2010) obtained from several monitoring stations and in situ measurements were used to identify African dust change in seasonal occurrence, their source origin, and their impact on surface PM10 concentrations. We pointed out that the Saharan dust contribution caused frequently the surpassing of the maximum number of days in excess of EU standard limits as well as of the maximum yearly average in the Mediterranean Tunisian coasts. The maximum daily concentration reaches 439 μg/m(3) during the Saharan events. The decrease in particulate levels recorded at the end of each event is due to the injection of European air masses and rainfalls. Primary pollutants peaks were much higher in winter than in summer which can be explained on the basis of the lower ventilation and mixing.

摘要

本文介绍了在突尼斯不同地点，当PM10（空气动力学直径小于10μm的颗粒物）浓度超过标准限值时，撒哈拉沙尘平流的演变情况。利用从多个监测站获取的气象和浓度数据（2004年至2010年）以及现场测量数据，来确定非洲沙尘季节性出现的变化、其来源以及对地表PM10浓度的影响。我们指出，撒哈拉沙尘的贡献经常导致超过欧盟标准限值的天数最大值以及突尼斯地中海沿岸的年度平均最大值。在撒哈拉沙尘事件期间，每日最大浓度达到439μg/m³。每次沙尘事件结束时记录到的颗粒物水平下降是由于欧洲气团的注入和降雨。冬季主要污染物峰值比夏季高得多，这可以基于较低的通风和混合情况来解释。
